Abstract

We present the results of a lattice study of the normalization constants and second moments of the light -cone distribution amplitudes of longitudinally and transversely polarized rho mesons. The calculation is performed using two flavors of dynamical clover fermions at lattice spacings between 0.060 fm and 0.081 fm, different lattice volumes up to m(pi)L = 6.7 and pion masses down to in, m(pi) = ...
